3.2 Principle of operation

The VEGAPULS 61 is a radar sensor for continuous level measure-

ment of liquids under simple process conditions.

Dependent on the application range, different versions are used:

l Level measurement of aggressive liquids in small vessels:

encapsulated antenna system

l Flow measurement in open flumes or gauge measurement of

bodies of water: Plastic horn antenna

l Products with an εr value ≥1.8: Standard electronics

l Products with an εr value ≥1.5, < 1.8; applications with very poor

reflective properties: Electronics with increased sensitivity

The actual values that can be reached depend on the measurement

conditions, the antenna system or the standpipe or bypass.

The antenna of the radar sensor emits short radar pulses with a

duration of approx. 1 ns. These pulses are reflected by the product

and received by the antenna as echoes. The running time of the radar

pulses from emission to reception is proportional to the distance and

hence to the level. The determined level is converted into an

appropriate output signal and outputted as measured value.

4.1 General instructions

With instruments with threaded process fitting, suitable tools must be

applied for tightening the hexagon.

Warning:

The housing must not be used to screw the instrument in! Applying

tightening force can damage internal parts of the housing.

Use the recommended cables (see chapter "Connecting to power

supply") and tighten the cable gland.

You can give your instrument additional protection against moisture

penetration by leading the connection cable downward in front of the

cable entry. Rain and condensation water can thus drain off. This

applies mainly to outdoor mounting as well as installation in areas

where high humidity is expected (e.g. through cleaning processes) or

on cooled or heated vessels.

Make sure that all parts of the instrument exposed to the process, in

particular the active measuring component, process seal and process

fitting, are suitable for the existing process conditions. These include

above all the process pressure, process temperature as well as the

chemical properties of the medium.

You can find the specifications in chapter "Technical data" and on the

type label.

4.2 Collar or adapter flange

For mounting the instrument on a socket, a combi compression flange

for DN 80 (ASME 3" or JIS 80) is also available for retro fitting.

Optionally, the instrument can be also equipped with an adapter flange

from DN 100 (ASME 4" or JIS 100).

With the housing versions plastic, aluminium single chamber and

stainless steel, the collar flange can be placed directly over the

housing. With the aluminium double chamber housing, retroactive

mounting in this way is not possible - the mounting type must be

specified with the order.

You can find drawings of these mounting options in chapter

"Dimensions".

4.3 Mounting preparations, mounting strap

The mounting strap enables simple mounting on the vessel wall or silo

top. It is suitable for wall, ceiling or boom mounting. Especially in open

vessels this is a very easy and effective way to align the sensor to the

bulk solid surface.

The strap is supplied unassembled and must be screwed to the sensor

before setup with three hexagon screws M5 x 10 and spring washers.

Max. torque, see chapter "Technical data". Required tools: Allen

wrench size 4.

There are two ways to screw the strap onto the sensor. Depending on

the selected version, the sensors can be swivelled in the strap as

follows:

l Single chamber housing

- Angle of inclination 180°, infinitely variable

- Angle of inclination in three steps 0°, 90° and 180°

l Double chamber housing

- Angle of inclination 90°, infinitely variable

- Angle of inclination in two steps 0° and 90°

4.4 Instructions for installation

For tight installation of the version with plastic horn antenna with

compression or adapter flange, the following conditions must be

fulfilled:

1 Use suitable flat seal, e.g. of EPDM with Shore hardness 25 or 50

2 Make sure the number of flange screws corresponds to the

number of flange holes

3 Tighten all screws with the torque stated in the technical data

The emitted radar impulses of the radar sensor are electromagnetic

waves. The polarisation plane is the direction of the electrical wave

component. By turning the instrument in the connection flange or

mounting boss, the polarisation can be used to reduce the effects of

false echoes.

The position of the polarisation plane is marked on the process fitting

of the instrument.

When mounting the sensor, keep a distance of at least 200 mm

(7.874 in) to the vessel wall. If the sensor is installed in the center of

dished or round vessel tops, multiple echoes can arise. These can,

however, be suppressed by an appropriate adjustment (see chapter

"Setup").

If you cannot keep this distance you should carry out a false echo

storage before setup. This applies mainly if buildup on the vessel wall

is expected. In this case, we recommend repeating a false echo

storage later with existing buildup.

Fig. 7: Mounting of the radar sensor on round vessel tops

In vessels with conical bottom it can be advantageous to mount the

sensor in the center of the vessel, as measurement is then possible

down to the lowest point of the vessel bottom.

Fig. 8: Mounting of the radar sensor on vessels with conical bottom

Do not mount the instruments in or above the filling stream. Make sure

that you detect the product surface, not the inflowing product.

Inflowing medium



Fig. 9: Mounting of the radar sensor with inflowing medium

A corresponding collar flange for DN 80 (ASME 3" or JIS 80) as well as

a suitable adapter flange are available for mounting VEGAPULS 61.

With the housing versions plastic, aluminium single chamber and

stainless steel, the collar flange can be placed directly over the

housing. With the aluminium double chamber housing, retroactive

mounting in this way is not possible - the mounting type must be

specified with the order.

Information:

The socket should be as short as possible and the socket end should

be rounded. Interfering reflections from the vessel socket are thus

minimised.

If the medium has good reflective properties, VEGAPULS 61 can also

be mounted on a longer socket piece. Recommended values for

socket heights are specified in the following illustration. You must carry

out a false echo storage afterwards.

Tip:

In new facilities it is useful to incline the vessel socket in the direction

of the outlet. False reflections from the vessel wall are thus reduced

and measurement all the way down to the bottom of the conical outlet

is possible.

possible also rounded. After installation you must carry out a false

echo storage.

The mounting location of the radar sensor should be a place where no

other equipment or fixtures cross the path of the microwave signals.

Vessel installations, such as e.g. ladders, limit switches, heating

spirals, struts, etc., can cause false echoes and impair the useful echo.

Make sure when planning your measuring site that the radar sensor

has a "clear view" to the measured product.

In case of existing vessel installations, a false echo storage should be

carried out during setup.

If large vessel installations such as struts or supports cause false

echoes, these can be attenuated through supplementary measures.

Small, inclined sheet metal baffles above the installations scatter the

radar signals and prevent direct interfering reflections.

Sensor orientation

Vessel installations



Fig. 16: Cover smooth profiles with deflectors

If there are agitators in the vessel, a false signal memory should be

carried out with the agitators in motion. This ensures that the interfering

reflections from the agitators are saved with the blades in different

positions.

Fig. 17: Agitators

Through the action of filling, stirring and other processes in the vessel,

compact foams that considerably damp the emitted signals may form

on the product surface.

If foams are causing measurement errors, the biggest possible radar

antennas, the electronics with increased sensitivity or low frequency

radar sensors (C band) should be used.

As an alternative, sensors with guided microwave can be used. These

are unaffected by foam generation and are best suited for such

applications.

l Do not weld through the pipe wall. The surge pipe must remain

smooth inside. Roughness and beads on the inside caused by

unintentional penetration should be removed since they cause

strong false echoes and encourage buildup

l Surge pipes must extend all the way down to the requested min.

l Diameter of holes ≤ 5 mm, any number OK, on one side or

completely through

l The antenna diameter of the sensor should correspond to the

inner diameter of the tube

5.1 Preparing the connection

Always keep in mind the following safety instructions:

l Connect only in the complete absence of line voltage

l If voltage surges are expected, install overvoltage arresters

Power supply and current signal are carried on the same two-wire

cable. The voltage supply range can differ depending on the

instrument version.

The data for power supply are specified in chapter "Technical data".

Provide a reliable separation between the supply circuit and the mains

circuits according to DIN VDE 0106 part 101.

Keep in mind the following additional factors that influence the

operating voltage:

l Output voltage of the power supply unit can be lower under

nominal load (with a sensor current of 20.5mA or 22mA in case of

fault message)

l Influence of additional instruments in the circuit (see load values in

chapter "Technical data")

The signal conditioning instruments VEGAMET and VEGASCAN have

digital sensor recognition. When connecting VEGAPULS 61, an up-to-

date software version of the signal conditioning instrument is required.

For a software update go to "Software" under "www.vega.com/

downloads".

The instrument is connected with standard two-wire cable without

screen. If electromagnetic interference is expected which is above the

test values of EN 61326-1 for industrial areas, screened cable should

be used.

For instruments with housing and cable gland, use cable with round

cross-section. A cable outer diameter of 5 … 9 mm (0.2 … 0.35 in)

ensures the seal effect of the cable gland. If you are using cable with a

different diameter, exchange the seal or use a suitable cable gland.

We generally recommend the use of screened cable for HART

multidrop mode.

With plastic housing, the NPT cable gland or the Conduit steel tube

must be screwed without grease into the threaded insert.

If screened cable is necessary, connect the cable screen on both ends

to ground potential. In the sensor, the screen must be connected

directly to the internal ground terminal. The ground terminal on the

outside of the housing must be connected to the potential equalisation

(low impedance).

If potential equalisation currents are expected, the connection on the

processing side must be made via a ceramic capacitor (e. g. 1 nF,

1500 V). The low frequency potential equalisation currents are thus

suppressed, but the protective effect against high frequency interfer-

ence signals remains.

5.2 Connect

The voltage supply and signal output are connected via the spring-

loaded terminals in the housing.

The connection to the indicating and adjustment module or to the

interface adapter is carried out via contact pins in the housing.

Proceed as follows:

1 Unscrew the housing cover

2 If an indicating and adjustment module is installed, remove it by

turning it slightly to the left.

3 Loosen compression nut of the cable entry

4 Remove approx. 10 cm (4 in) of the cable mantle, strip approx.

1 cm (0.4 in) of insulation from the ends of the individual wires

5 Insert the cable into the sensor through the cable entry

Information:

Solid cores as well as flexible cores with cable end sleeves are

inserted directly into the terminal openings. In case of flexible cores

without end sleeves, press the terminal head with a small screwdriver;

the terminal opening is freed. When the screwdriver is released, the

terminal closes again.

7 Check the hold of the wires in the terminals by lightly pulling on

them

8 Connect the screen to the internal ground terminal, connect the

outer ground terminal to potential equalisation

9 Tighten the compression nut of the cable entry. The seal ring must

completely encircle the cable

10 Screw the housing cover back on

The electrical connection is finished.

Information:

The terminal block is pluggable and can be removed from the

electronics. To do this, lift the terminal block with a small screwdriver

and pull it out. When inserting the terminal block again, you should

hear it snap in.

6.3 Parameter adjustment

Through the parameter adjustment the instrument is adapted to the

application conditions. The parameter adjustment is carried out via an

adjustment menu.

The main menu is divided into five sections with the following

functions:

Setup: Settings, e.g., for measurement loop name, medium, applica-

tion, vessel, adjustment, signal output

Display: Settings, e.g., for language, measured value display, lighting

Diagnosis: Information, e.g. on the instrument status, pointer,

reliability, simulation, echo curve

Further settings: Instrument unit, false signal suppression, linear-

isation curve, reset, date/time, reset, copy function

Info: Instrument name, hardware and software version, calibration

date, instrument features

Information:

In this operating instructions manual, the instrument-specific param-

eters in the menu sections "Setup", "Diagnosis" and "Additional

settings" are described. The general parameters in these menu

section are described in the operating instructions manual "Indicating

and adjustment module".

You can find in the operating instructions manual "Indicating and

adjustment module" also the description of the menu sections

"Display" and "Info".

In the main menu point "Setup", the individual submenu points should

be selected subsequently and provided with the correct parameters to

ensure the optimum adjustment of the measurement. The procedure is

described in the following.

Each medium has different reflection properties. With liquids, further

interfering factors are fluctuation product surface and foam generation.

With bulk solids, these are dust generation, material cone and

additional echoes from the vessel wall.

To adapt the sensor to these different measuring conditions, the

selection "Liquid" or "Bulk solid" should be made in this menu item.

Main menu

Setup/Medium



36499-EN-120301

Through this selection, the sensor is adapted perfectly to the product

and measurement reliability, particularly in products with poor

reflective properties, is considerably increased.

Enter the requested parameters via the appropriate keys, save your

settings with [OK] and jump to the next menu item with the [ESC] and

the [->] key.

In addition to the medium, also the application, i.e. the measuring site,

can influence the measurement.

With this menu item, the sensor can be adapted to the applications.

The adjustment possibilities depend on the selection "Liquid" or "Bulk

solid" under "Medium".

The following options are available when "Liquid" is selected:

The selection "Standpipe" opens a new window in which the inner

diameter of the applied standpipe is entered.

Caution:

If a separation of liquids with different dielectric figure occurs in the

vessel, for example through condensation, the radar sensor can detect

under certain circumstances only the medium with the higher dielectric

figure. Keep in mind that layer interfaces can cause faulty measure-

ments.

If you want to measure the total height of both liquids reliably, please

contact our service department or use an instrument specially

designed for interface measurement.

the [->] key.

Because a radar sensor is a distance measuring instrument, the

distance from the sensor to the product surface is measured. To have

the real product level displayed, an allocation of the measured

distance to the percentage height must be made. To carry out this

adjustment, the distance is entered with full and empty vessel. If these

values are not known, an adjustment with the distance values, e.g.

10 % and 90 % is also possible. Starting point for these distance

specifications is always the seal surface of the thread or flange. By

means of these settings, the real level is calculated.

The real product level during this adjustment is not important, because

the min./max. adjustment is always carried out without changing the

product level. These settings can be made ahead of time without the

instrument having to be installed.

Proceed as follows:

1 Select the menu item "Setup" with [->] and confirm with [OK]. Now

select with [->] the menu item "Min. adjustment" and confirm with

[OK].

2 Edit the percentage value with [OK] and set the cursor to the

distance from the sensor to the vessel bottom) corresponding to

the percentage value.

5 Save settings with [OK] and move with [ESC] and [->] to the max.

Proceed as follows:

1 Select with [->] the menu item max. adjustment and confirm with

[OK].

2 Prepare the percentage value for editing with [OK] and set the

cursor to the requested position with [->].

3 Set the requested percentage value with [+] and save with [OK].

The cursor jumps now to the distance value.

4 Enter the appropriate distance value in m (corresponding to the

percentage value) for the full vessel. Keep in mind that the max.

level must lie below the min. distance to the antenna edge.

5 Save settings with [OK]

Min. and max. measured values are saved in the sensor. The values

are displayed in the menu item "Peak values".

When non-contact level sensors are used, the measurement can be

influenced by the respective process conditions. In this menu item, the

measurement reliability of the level echo is displayed as dB value. The

measurement reliability equals signal strength minus noise. The higher

the value, the more reliable the measurement. With a functioning

measurement, the values are > 10 dB.

The "Echo curve" shows the signal strength of the echoes over the

measuring range in dB. The signal strength enables an evaluation of

the quality of the measurement.

The "False signal suppression" displays the saved false echoes (see

menu "Additional settings") of the empty vessel with signal strength in

"dB" over the measuring range.

A comparison of echo curve and false signal suppression allows a

more accurate conclusion on measurement reliability. The selected

curve is continuously updated. With the [OK] key, a submenu with

zoom functions is opened:

l "X-Zoom": Zoom function for the meas. distance

l "Y-Zoom": 1, 2, 5 and 10x signal magnification in "dB"

l "Unzoom": Reset the presentation to the nominal measuring range

with single magnification

With the function "Echo curve memory" the echo curve can be saved

at the time of setup. This is generally recommended; for using the

AssetManagement functions it is absolutely necessary. If possible, the

curve should be saved with a low level in the vessel.

With the adjustment software PACTware and the PC, the high

resolution echo curve can be displayed and used to recognize signal

changes over the operating time. In addition, the echo curve of the

setup can be also displayed in the echo curve window and compared

with the actual echo curve.

The following circumstances cause interfering reflections and can

influence the measurement:

l High sockets

l Vessel installations such as struts

l Agitators

l Buildup or welded joints on vessel walls

Note:

A false signal suppression detects, marks and saves these false

signals so that they are no longer taken into account for level

measurement.

This should be done with a low level so that possible interfering

reflections can be detected.

Proceed as follows:

1 Select the menu item "Additional settins" with [->] and confirm with

[OK]. With [->] you have to select the menu item "False signal

2 Confirm again with [OK].

3 Confirm again with [OK].

4 Confirm again with [OK] and enter the actual distance from the

sensor to the product surface.

5 All interfering signals in this section are detected by the sensor

and stored after confirming with [OK].

Note:

Check the distance to the product surface, because if an incorrect (too

large) value is entered, the existing level will be saved as false signal.

The filling level would then no longer be detectable in this area.

If a false signal suppression is already created in the sensor, then the

following menu window appears when selecting "False signal

suppression":

The menu item "Delete" is used to completely delete an already

created false signal suppression. This is useful if the saved false signal

suppression no longer matches the metrological conditions in the

vessel.



36499-EN-120301

The menu item "Extend" is used to extend an already created false

signal suppression. This is useful if a false signal suppression was

carried out with a too high level and not all false signals could be

detected.When selecting "Extend", the distance to the product surface

of the created false signal suppression is displayed. This value can

now be changed and the false signal suppression can be extended to

this range.

A linearization is necessary for all vessels in which the vessel volume

does not increase linearly with the level - e.g. in a horizontal cylindrical

or spherical tank - and the indication or output of the volume is

required. Corresponding linearization curves are preprogrammed for

these vessels. They represent the correlation between the level

percentage and vessel volume.

By activating the appropriate curve, the volume percentage of the

vessel is displayed correctly. If the volume should not be displayed in

percent but e.g. in l or kg, a scaling can be also set in the menu item

"Display".

Caution:

Note the following if the instrument with corresponding approval is

used as part of an overfill protection system according to WHG:

If a linearisation curve is selected, the measuring signal is no longer

compulsorily linear proportional to the level. This must be taken into

consideration by the user, particularly when adjusting the switching

point on the level switch.

With a reset, certain parameter adjustments carried out by the user are

reset.

6.4 Saving the parameter adjustment data

It is recommended noting the adjusted data, e.g. in this operating

instructions manual and archive them afterwards. They are hence

available for multiple use or service purposes.

If the instrument is equipped with an indicating and adjustment

module, the data in the sensor can be saved in the indicating and

adjustment module. The procedure is described in the operating

instructions manual "Indicating and adjustment module" in the menu

item "Copy sensor data". The data remain there permanently even if

the sensor power supply fails.

The following data or settings for adjustment of the indicating and

adjustment module are saved:

l All data of the menu "Setup" and "Display"

l In the menu "Additional settings" the items "Sensor-specific units,

temperature unit and linearization"

l The values of the user programmable linearization curve

The function can also be used to transfer settings from one instrument

to another instrument of the same type. If it is necessary to exchange a

sensor, the indicating and adjustment module is inserted into the

replacement instrument and the data are likewise written into the

sensor via the menu item "Copy sensor data".

7 Setup with PACTware36499-EN-120301

Note:

With power supply units with integrated HART resistance (internal

resistance approx. 250 Ω), an additional external resistance is not

necessary. This applies, e.g. to the VEGA instruments VEGATRENN

149A, VEGAMET 381, VEGAMET 391. Common Ex separators are

also usually equipped with a sufficient current limitation resistance. In

such cases, the interface converter can be connected parallel to the

4 … 20 mA cable (dashed line in the previous illustration).

7.2 Parameter adjustment with PACTware

For parameter adjustment of the sensor via a Windows PC, the

configuration software PACTware and a suitable instrument driver

(DTM) according to FDT standard are required. The up-to-date

PACTware version as well as all available DTMs are compiled in a

DTM Collection. The DTMs can also be integrated into other frame

applications according to FDT standard.

Note:

To ensure that all instrument functions are supported, you should

always use the latest DTM Collection. Furthermore, not all described

functions are included in older firmware versions. You can download

the latest instrument software from our homepage. A description of the

update procedure is also available in the Internet.

Further setup steps are described in the operating instructions manual

"DTM Collection/PACTware" attached to each DTM Collection and

which can also be downloaded from the Internet. Detailed descriptions

are available in the online help of PACTware and the DTMs.

Prerequisites



36499-EN-120301

All device DTMs are available as a free-of-charge standard version

and as a full version that must be purchased. In the standard version,

all functions for complete setup are already included. An assistant for

simple project configuration simplifies the adjustment considerably.

Saving/printing the project as well as import/export functions are also

part of the standard version.

In the full version there is also an extended print function for complete

project documentation as well as a save function for measured value

and echo curves. In addition, there is a tank calculation program as

well as a multiviewer for display and analysis of the saved measured

value and echo curves.

The standard version is available as a free-of-charge download under

http://www.vega.com. The full version is available on CD from the

agency serving you.

9.1 Maintaining

If the device is used correctly, no maintenance is required in normal

operation.

9.2 Measured value and event memory

The instrument has several memories which are available for

diagnosis purposes. The data remain even with voltage interruption.

Up to 70,000 measured values can be stored in the sensor in a ring

memory. Each entry contains date/time as well as the respective

measured value.

Stored values are for example:

l Original sensor value

l Filling height

l Signal current

l Meas. reliability

l Electronics temperature

The requested values and recording conditions are set via a PC with

PACTware/DTM or the control system with EDD. Data are thus read

out and also reset.

Up to 500 events are automatically stored with a time stamp in the

sensor (non-deletable). Each entry contains date/time, event type,

event description and value.

Event types are for example:

l Modification of a parameter

l Switching on and off times

l Status messages

l Error messages

The data are read out via a PC with PACTware/DTM or the control

system with EDD.

The echo curves are stored with date and time and the corresponding

echo data. The memory is divided into two sections:

Echo curve of the setup: This is used as reference echo curve for the

measurement conditions during setup. Changes in the measurement

conditions during operation or buildup on the antenna can thus be

recognized.

The echo curve of setup is stored via:

l PC with PACTware/DTM

l Control system with EDD

l Indicating and adjustment module

Measured value memory

Event memory

Echo curve memory


9 Diagnosis, Asset Management and service36499-EN-120301

Further echo curves: Up to 10 echo curves can be stored in a ring

buffer in this memory section.

Additional echo curves are stored via:

l PC with PACTware/DTM

l Control system with EDD

9.3 Asset Management function

The instrument features self-monitoring and diagnosis according to NE

107 and VDI/VDE 2650. In addition to the status messages in the

following tables there are more detailed error messages available

under the menu item "Diagnosis" via the indicating and adjustment

module, PACTware/DTM and EDD.

The status messages are classified in the following categories:

l Failure

l Function check

l Out of specification

l Maintenance requirement

and explained by pictographs:

41 2 3

Fig. 37: Pictograms of the status messages

1 Failure - red

2 Function check - orange

3 Out of specification - yellow

4 Maintenance - blue

Failure: Due to a malfunction in the instrument, a failure message is

outputted.

This status message is always active. A deactivation by the user is not

possible.

Function check: The instrument is in operation, the measured value is

temporarily invalid (for example during simulation).

This status message is always active. A deactivation by the user is not

possible.

Out of specification: The measured value is unstable because the

instrument specification is exceeded (e.g. electronics temperature).

This status message is inactive by default. Activation by the user via

PACTware/DTM or EDD is possible.

Status messages



36499-EN-120301

Maintenance: Due to external influences, the instrument function is

limited. The measurement is affected, but the measured value is still

valid. Plan in maintenance for the instrument because a failure is

expected in the near future (e.g. due to buildup).

This status message is inactive by default. Activation by the user via

PACTware/DTM or EDD is possible.

The following table shows the error codes in the status message

"Failure" and gives information on the reason and rectification. Keep in

mind that some information is only valid with four-wire instruments.

9.4 Remove interferences

The operator of the system is responsible for taking suitable measures

to rectify faults.

The first measures are:

l Evaluation of fault messages via the indicating and adjustment

module

l Checking the 4 … 20 mA signal

l Treatment of measurement errors

Further comprehensive diagnosis possibilities are offered by a PC with

the software PACTware and suitable DTM.

In many case, the failure reasons can thus be determined and faults

rectified.

Connect a handmultimeter in the suitable measuring range according

to the wiring plan. The following table describes possible errors in the

current signal and helps to remove them:
